Question

x=5x-13 solucion y comprovacion paso a paso xfa

Answer 1

Resolver.
x = 5x - 13
x + 13 = 5x
13 = 5x - x
13 = 4x
13/4 = x

Solución.
x = 13/4

Comprobación.

x = 5x - 13
13/4 = 5(13/4) - 13
13/4 = 65/4 - 13
13/4 = 65/4 - 52/4
13/4 = (65 - 52)/4
13/4 = 13/4

Answer 2

$x = 5x - 13 \\ trasponemos \: terminos \\ 13 = 5x - x$
$4x = 13 \: despejamos. \\ x = \frac{13}{4}$
Respuesta:
$x = \frac{13}{4} \\ comprobacion$
$5x - x = 13 \\ 5 \times ( \frac{13}{4}) - \frac{13}{4} = 13 \\ \frac{65}{4} - \frac{13}{4} = 13$
$efectuamos \\ \frac{65}{4} - \frac{13}{4} = 13 \\ \frac{65 - 13}{4} = 13$
$\frac{52}{4} = 13 \\ 13 = 13$
